Appendix C: LDAP RFCs & X.500

The following RFCs and X.500 series specifications describe LDAP or are relevant to it.

The ITU-T (the 800 lb gorilla of the standards world) have lots of specs on X.500 (each of which costs you lots of money). To be fair you can get some free specs but their policy seems to keep changing. They do however seem to be publishing their ASN.1 definitions for free (X.519 example).

Note: The main repository for RFCs is maintained by the IETF, text versions (the normative reference) may be viewed at www.ietf.org/rfc/rfcXXXX.txt or www.rfc-editor.org/rfc/rfcXXXX.txt (where XXXX is the 4 digit RFC number - left padded with zeros as necessary). Currently published RFCs are pointed to https://www.rfc-editor.org/info/rfcXXXX (where XXXX is the 4 digit RFC number - left padded with zeros as necessary) which contains various information and links to the text (normative) reference and a PDF (non-normative) version. The RFC may also be viewed at http://datatracker.ietf.org/doc/rfcXXXX/ (where XXXX is the 4 digit RFC number - left padded with zeros as necessary) which also contains various RFC status information together with a list of alternative formats, such as, text, PDF and HTML (this is the working area version of the document). Finally, there is now a searchable RFC list.

<ingrained habit> The RFC links below yield a plain text version which was copied to our site when the RFC was issued. We started this service a long time ago when the world was young, RFCs were maintained in some strange places, occasionally moved location, and performance and reliability of the repositories was very variable (being generous). None of these conditions apply today, far from it. Nevertheless, we persist in our ingrained habits for no particularly good reason (old dog...new tricks..). If you want/prefer/need more choice you are advised to use one of the links identified above, if, however, you just want to read the blasted RFC, feel free to click the links below.</ingrained habit>
